Low Temperature Alarm / Overcooling Condition
Symptom
Buttons on the freezer control panel do not respond or respond intermittently.
Unresponsive Touch Controls / Keypad Failure
Symptom
Excessive frost buildup on shelves, walls, and food items inside the freezer.
Excessive Frost / Moisture Ingress
Symptom
Freezer cools but temperature fluctuates widely, causing partial thawing and refreezing.
Temperature Instability
Symptom
Freezer display is blank or unresponsive, but the unit may still be cooling.
User Interface / Display Failure
Symptom
Freezer door does not close or seal properly; door pops open or gaps are visible.
Door Alignment / Gasket Failure
Symptom
Freezer door is hard to open immediately after closing; a vacuum seems to form.
Door Vacuum / Pressure Equalization
Symptom
Freezer emits a musty or moldy odor inside the cabinet.
Odor Contamination / Biological Growth
Symptom
Freezer emits a strong chemical or refrigerant-like odor.
Possible Refrigerant Leak or Contamination
Symptom
Freezer interior fan runs, but there is little or no airflow from vents.
Airflow Restriction / Blocked Vents
Symptom
Freezer interior is cold but the alarm beeps and high temperature indicator flashes intermittently.
False High Temperature Alarm
Symptom
Freezer interior light stays on even when the door is closed, causing warming and condensation near the light.
Door Switch Stuck or Misaligned
Symptom
Freezer interior light works but compressor and fan do not run; no humming or clicking sounds.
Control Not Calling for Cooling / Standby State
Symptom
Freezer is leaking water onto the floor from the front or underneath.
Defrost Drain Blockage / Water Management Issue
Symptom
Freezer is making a loud buzzing or humming noise from the compressor area.

Compressor Not Running / No Cooling
Symptom
Freezer runs but does not get cold enough; temperature stays above -10°C (14°F).
Insufficient Cooling / Partial Loss of Refrigeration
Symptom
Freezer runs continuously without shutting off, even when interior is very cold.
Continuous Run / Short Cycling Control
Symptom
Freezer trips the household circuit breaker or blows fuses when it starts.
Electrical Short or Overcurrent
Symptom
Interior light does not turn on when the freezer door is opened.
Interior Light Circuit Failure
Symptom
Thick sheet of ice forming on the freezer floor.
